When Creative Cloud attempts to update CS6 I get the following error:Update FailedErrors encountered during installation (U44MIP7)

This is really unfortunate that you are facing issues with PS updates.

Please confirm if this error is coming due to ExMan update failure. Ps must be updated now, Verify the same by Ps->About Photoshop.
Try installing latest ExMan from here:

After successful installation try updating again through Help->Update.
